To all wi/tom t may concern: l Be it known that-I, THoMAs THOMPSON, a citizen of the United States, residing at Makoti, in the county of Ward and. State of North Dakota, have invented certain new and useful Improvements in Locks; and I do hereby declare the following to'be a full, clear, and exact description of the invention, such as will enable others'skilled in the art to which it appertains to make and use the same. j

This invention relates to a lock and the invention is shown as applied to different forms oflocks. The invention herein disclosed isan improvement upon that disclosed and claimed in my previously granted Patent "No, 1,311,102, granted July 22nd,` 1919. y

It 'is an object of this invention to simplify the construction shown in'V said patent and improve the sameby forming the operating bar or outer member' of the lock with an integral head which, when the lock is closed, will cover the keeper and portion ofthelatch engaging the same. p f

'It `'s' also an objectof the invention to provide the latch and theJ sides of theienclosing casing with inter-engaging portions forming a locking means which', when the lock is closed,will form one continuoussur- It is still another object of the'invention to so construct thelock thatthe same can be used as a locking or disengaging link ofa chain.

These and otherobjects of the invention will-appearfrom the following description made in connection with the accompanying drawings, in whichlike reference characters refer to the same parts in the different views thereof, and in which--r Fig. 1 is a plan view of one form of a lock;" f 'g Fig. 2 is a view in sidefelevation of the same partly in secti0n',fshowing the lock par- A Fig. v3 is a vview in side elevation showing the lock in the forni of a chain link, the parts being shown in different position in dottednlines; f' v Figl is a section on the line i-#l of Fig. 3 looking'in the direction of the arrows;

prises a. casing 4 having a flange extendingv Specification of Lettersliatent.Y Patented Apr. 4, 1922. Application filed April 2.5,

1921. v serial No. 464,293.

Referring to the drawings, particularly to `l `igs. 1 and 2, two movable parts 1 and 2 are shown which may represent portions of the door and door casing or any other mov'- able parts vwhich is desired .to lock together. The keeper inemberfis shown as 3 v provided with a flange and an upwardly inclmed lip'portion 3%, this keeper being secured tothe member 1 by suitable nutted bolts passing through holes in the flange The latch portion of the lockcom ytherefrom "alining'with the flange on the keeper 3, whichllangeis also'adapted to be secured to the member-2 by nutted vbolts passing through openings therein. l The casing 4 has spaced side portions l extending upwardly from the flange thereof and a bar 5 is providedwith spaced rib members 5fL on the under or inner side thereof by means of which it is pivoted to the side portions leV 'of the vcasing by a suitably riveted or headed pivot member. The member 5 hasits end adjacent the pivot bent downwardly so that when it is in closed position it will aline with the ends of the members 4r@ and Vform a closed casing. A latch mem ber 6 is pivoted to the bar 5 by spaced ribs 6a through which andthe ribs 5, the pivot 7, suitably riveted or otherwise secured, ex tends. This pivot -7 is located 'below the pivot connecting the bar 5 to the casing so that the same` bears thereto. The latch member extends forwardly and vis adapted vto seat over the por tion 3of the keeper,` the front end of the latch being bent or formed. with a down? latch also comprises at its front end the side walls 6 extending continuous `with the front portion thereof, which walls are formed with a vprojecting portion'at the rear sides thereof, the end of which'is formed as a point or V-shaped projection 6b. The frontend of the side portions 4 areformed with a notch of the same shape as the projection 6" and adapted to receive the samewhen the lock is closed. The front portion of said projection on the latch is formed with an inclined edge. `The bar 5 isalso formed at its front end with downwardly extending side portions 5l V*which extend continuous with the" front portion which is curved downwardly and the lower edge ofthe same, as well as the edge of the side por- `an eccentric relation Cil tions are adapted to engagewith the flange 3.01 the keeper. The rear edge of the side portions 5b are formed-on an incline adapted to engage when the'lock is closed withV the'incline on the front edge of the projection on the latch. The extreme rearendy of the side portions 5b are formed of rectangular shape and the said ends are adapted to engage with the end of the casing Ll, when.

cannot be lifted when the lock is closed, the

same is provided with a pivoted button 8 of oblong shape having'a stem with aprojecting` shoulder Sby which it .is secured to the inner surface of the bar 5 by shouldered plates 9 riveted to said bar. The said stem extends through the bar 5 and is formedV with a keyhole to receive a. key by which the same may be turned. Then the barV 5 is moved rto closed position the button 9 will l pass through a slot 10 formed in the top ot the latch G and when said button is turned, the ends thereof will engage under the top 'of the member 10 aty the sides of the slot and will prevent the bar5 from being lifted. Owing to the eccentric connection between the latch@ and bar 5 it will be readily seen that when the bar 5 is raised the latch 6 will be moved outwardly longitudinally, as shown in Fig. 2. The. end ot' the Abar 5 also projectsunder the lugs 6a upward movement'of the bar 5 will swing` the latch 6 upwardly about its pivot to disengage the same from the keeper. l In Figsp and G, the lock is vshown formed as a link of a chain and in these figures the casing 11 comprisesa plate 'formed in substantially U-shape, vone end thereof being rounded and provided with an aperture 12 'to receive-the succeeding link of the chain. A. bar 13 corresponding to the bar 5 isjplvob cd by asuitable pivot 14 between the sides o'l'fcasing 11. lt will be noted that the trout end of the casing 11 is lslightly inclined and oneV side thereof is provided with a V-shaped notch 11a. In its frontend, the bar v13 is formed with depending parallel sides 13a through which aVhook-orming slot 15 extends. The rear edges of the sides 18 arey formed on a similar angle to the front sides of the casing 11 and are adapted to approximately engage therewith. A latch member 16 formed with a hook shaped front end is pivotedto the bar 5 lby a suitable pivot 17. This latch slides vbetween the bar 5 and one Y side of the 'casing 11 and has a projecting l which, when triangular or V-shaped lug 16 thereonY the lock or link is closed is so th at continued adapted to engage in the notch 11a, as shown in Fig. 3. lt willbe seen that when the. link is closedthe outer surfaces ot' the sides 13a andll aswell as the lock 11a., all lie in 13 and the latch l16. llVhen thelink isclosedy it will be seen that the same cannot beopened by longitudinal stress placed on the links.l

The form yof lock shown in Figs. 1 and l Y and V,the sameV will bel firmly held by the headed portion ol." the barA can be used on doors of various kinds or on r trunks, suit cases, or grips. The s aidlock when closed -forms a neat and ycompact eli-- closed structure. y The link shown in Figs. 3 and also forms va smooth compactstruc-A ture when closed and which can` also@ be quickly and easily opened whenit is desired to disengage the'same. y

. lt will, of course, be understood. that yva-j rions changes may-be made inthe form, der,k

tails and arrangementlotthe parts without departing from thescope of applicants in.
